The flow of water at each outlet, at which the foam compound should be mixed, is recorded by a flow meter. The DIGIMATIC is controlled and the corresponding foam compound quantity mixed depending on the set flow and proportioning ratio.

The system consists of membrane pumps and achieves a minimum proportioning volume of only 0.1 l/min. An additional impeller pump guarantees the best possible external suction.

The proportioning rate can be adjusted continuously from 0.1% to 6%.

There is also the option of selectively injecting at two different injection points.

Can be selectively primed from three foam compound sources (two foam compound tanks and one external suction).

This system offers a very wide spectrum of proportioning volumes. A highly efficient electric motor generates a maximum proportioning volume of 42 l/min. Furthermore, the motor can be very precisely controlled, whereby very small revolutions are possible. This means that the membrane pump can deliver a minimum proportioning volume of only 0.1 l/min. An additional impeller pump guarantees the best possible external suction.

Broad application range due to wide spectrum of minimum and maximum proportioning volumes (from wetting agent operation with 0.1 l/min up to turret operation or operation of multiple discharge outlets with up to 42 l/min of foam compound)

Conventional foam attack without additional proportioning

Indication of the proportioning ratio incl. assistance, if exceeding the working range

Retention of the set proportioning ratio, regardless of pressure and flow

All foam compounds with a viscosity of 150 cSt have a wide application range (foam compounds with higher viscosity available upon request)

The system consists of two membrane pumps, whereby one of the pumps can be switched off for low proportioning quantities (from 0.1 l/min). An additional impeller pump guarantees the best possible external suction.

Use of multiple foam concentrate sources (two foam tanks and draft operation possible) - provision of foam compounds for the most varied of operating conditions - one proportioning ratio can be pre-defined per foam concentrate source

Various injection points can be selected (up to 2 with DIGIMATIC22, up to 3 with DIGIMATIC42)
